This is good, but I find it to be fairly vague. It seems like you have a message, but it never really comes out. I think this could serve better as an extended poem with more imagery involved. It just kind of comes up empty to me. I desire more from the poem. I think strong imagery is the answer here. With a fast climatic build up to the last 2 stanzas.

Also, "them" seems to come out of nowhere. This is where the imagery can really fill your gaps. Who is "them"?

It's seems to me you had a great idea when you first started this, then you sorta gave it a "shrug" and came up with something repetitive to fill in that gap. Elaboration of this would have helped it enormously I think. As the three first stanzas are great.

But it's your idea, and I don't know if this was intentional or why you decided to end it like that. It's not bad, sure the end works, as this piece speaks more of a personal outlet rather then something which you wanted us to be interested in. Not to be rude
